How To Age Up Pets in The Sims 4

Pets were added to the Sims 4 in The Sims 4: Cats & Dogs! We love our pets, but sometimes you want to choose when your pets age up instead of letting the game decide for you. Don’t worry! You CAN control their age using treats or cheats in the game! This is how:

Age Up Pets with Treats

The game has an “age up treat”, which you can purchase or get your Sim to craft themselves.

How To Purchase the Age-Up Treat

Best method:

1. Visit a Vet Clinic lot in game
2. Click on the animal treats vending machine and select “Purchase Pet Items”
3. Purchase the “Age-Up Treat” (it’s brown!) for 150 Simoleons via the menu that appears
4. Feed the treat to your pet and they will age up

You cannot buy the treat directly from build/buy mode, but you can buy one of the vending machines called Dr. Budget-Bandage’s Medico-Vendo-Thingo (950 simoleons) and Dr. Magi-Heal’s Medical Vend-o-matic (2,400 simoleons). The method of buying the vending machine yourself to purchase the age-up treat works best if your Sim is the owner of a vet clinic themselves.

Craft the Age-Up Treat

For this method your Sim will need level 6 of the veterinarian skill!

1. Purchase one of the veterinarian craft tables from build/buy mode. The options are:
   1. Dr. Budget-Bandage’s Medicine Craftink (650 simoleons)
   2. Dr. Magi-Heal’s Medicine Craft-o-matic (1,200 simoleons)
2. Select the table and choose to craft the “Age-Up Treat”. This option will appear if your Sim is at least level 6 in the veterinarian skill.

If you’d like to cheat your Sim’s veterinarian skill, then after activating cheats (Step one in the next section of this post!) type “stats.set_skill_level Major_Vet10” into the cheats bar and press enter. You can replace the number 10 with whichever level that you would like your Sim to have in the skill (10 is the maximum)!

Age Up Pets with Cheats

When you shift click on a Sim (pets included) there is an option to “Modify in CAS”, which lets you change everything about their appearance but you can’t change their age. In order to be able to change their age you will need to follow these steps:

1. Activate cheats in the Sims 4 by pressing down on the keys SHIFT + CTRL + C (for console players: hold down all four shoulder buttons). Then type in “testingcheats true” and press enter
2. Type into the bar cas.fulleditmode and press enter
3. Press SHIFT while clicking on your pet and select “Modify in CAS”

Now you can change the age of your pet as well as changing anything else you’d like about them! When you’re done just click on the tick in the bottom right hand corner of the screen to save your changes and return to live mode.

How to Age Down Pets in the Sims 4

Both methods above apply to aging down your pets too! For the treats method, you simply need to select “Age-Down Treat” (it’s orange!) in the menu instead and feed it to your pet.

How Do Pets Age in the Sims 4

Pets age up on their own in the Sims 4 following the gameplay lifespan that you have set in your settings under the gameplay category (i.e. Short, Normal, or Long).

Pets have three life stages: kitten/puppy, adult, and elder.

Both methods of ageing your pets up or down will change their life stage by one level.

Note that pets won’t age up whilst they are pregnant!

Can You Turn Off Pet Aging in the Sims 4?

Yes! Pets in the Sims 4 follow the ageing settings for your Sims. How to turn off ageing:

1. Open settings and select the gameplay menu from the side bar
2. Under the “Auto Age (Played Sims)” option you can either select “No” to stop ageing for all Sims or “Only Active Household” to only stop ageing for your active households including their pets!
